PICKING-STECK FOR UNDEBEICK-EGOMS.

Specification of Letters Patent.

Patented. May 4, l 909.

Application. filed November 17, 1908. Serial No. 463,036.

To all whom it may concern:

Be it known that we, -`NALTEP. BOND and Jnssn BAXENDALE, both subjects of the King of Great Britain and ireland, and both residents of Bolton, in the county of Lancaster, England, have invented new and useful Improvements in Picking-Sticks for Underpick-Looms, of which the following is a speci- 'lication These improvements relate to the picking sticks or picking shafts of underpick looms, and their object is to so construct such sticks or shafts as to increase their durability, to strengthen them so as to avoid the cost of frequent renewals, and to enable the renewal of the tip to be effected at a very small cost. Such sticks as at present commonly made and used consist of a properly shaped piece of wood, the lower end of which is carried in and secured to a rocking socket which is suitably operated to actuate the stick and the upper end of which enters into the shuttle box to impart motion to the picker and the shuttle. near a third of their length downward from the tip or at about where they enter their shuttle boxes. To reduce the disadvantages following on such breakages it has before now been proposed to mount the ordinary wooden picker stick in a metal sheath along which it could be adjusted so that as part of the stick was broken off the remainder could be moved along the sheath to enter the shuttle box and act on the picker. The disadvantage of such an arrangement is the necessity of properly shaping the broken end before it can be engaged with the picker.

In carrying our invention into effect wev make breakages impossible or reduce the risk of breakages to a minimum by dispensing with the wooden picking stick, and replacing it by a suitable metallic one, of a length insufficient to reach into the shuttle-box, and provided with a wooden or non-metallic tip or end to enter the shuttle-box. rlhe metallic picker stick has a length which extends upward past the point where breakage heretofore usually occurred as above explained, and may be secured in a rocking socket in the same manner that a wooden one is at present or it may be otherwise suitably mounted and operated. T he wooden or non-metallic end or tip of the stick may be composed of the same wood as is at present commonly used in wooden picking sticks, and is removably attached to the metallic part so as to be readily Such sticks frequently break at or' removed therefrom when worn and be replaced by a new tip.

A preferred form of our improved picker stick is illustrated in the accompanying drawings, in which- Figure l is an elevation of a picking stick formed according to this invention. Fig. 2 shows a cross section of the same stick along the line X-Y Fig. l. liig. 3 shows the saine stick in elevation at right angles to the view shown in Fig. 1.

Referring to the drawings, the stick is composed of or formed with a metallic main part A which is channel shaped in cross section. This part may conveniently be stamped out of sheet metal. Y To its upper end is attached the removable wooden tip B which enters the shuttle box and operates the picker in the usual manner. This tip may be secured to the part A by screws or equivalent fastening devices as desired. In a preferred construction and as illustrated the part A is filled with a wooden filling C, the upper end of which is formed with a tapered groove or recess C1 extending transversely through it. The inner end of the tip is formed with a corresponding tapered part B1 which enters into and engages with the recess in the filling C. When the parts are assembled and the tip B is in place the whole may be firmly held together by placing a sheet metal cap D in place over the upper end of the part A and clamping or holding all the different parts together by screws and nuts E, El. rihe lower end of the composite stick has screw holes F by which it may be secured to the rocking socket in the manner usual with picking sticks.

As will be seen, the recess (l1 in the lling, is of a general or average cross sectional area less than a similar area of the interior of the channel bar, and that the insertible portion of the tip substantially fits said recess. By this construction the insertible portion is practically incorporated with the iilling, the whole producing a structure in which the tip is braced against strains by the filling as well as by the end walls of the channel bar, owing to the fact that the lling is of a width to extend from one wall of the channel bar to the other. In addition, the provision that the tip has a cross sectional area of its exposed surface adjaeent the juncture thereof with the insertible portion greater than that of a similar area of the insertible portion, thereby forming shoulders which rest against the ends of the lling and of the channel bar provides -an additional bracing against a rocking movement of the tip.

It is evident from the foregoing description and illustrations that the main part A of the improved picker is practically unbreakable and that if the tip B breaks or Wears out it can he simply and easily replaced at a minimum cost.

le clainiz-d 1. A picking stick for looms comprising a rigid metallic channel har having a filling, said iilling having a recess extending longitudinally of the stick and of a general cross sectional area less than a similar area of the interior of the channel' har, a tip seatahle Within said recess, said tip having a cross sectional arca of its exposed surface adjacent the juncture thereof with the insertihle portion greater than that of a similar area of the insertible portion, the insertihle portion substantially fitting said recess and removable means for retaining the tip in its inserted position.

2. A picking stick for looms comprising a rigid metallic channel bar having a filling, said illing having a recess extending longitudinally of the stick and of a general cross sectional area less than a similar area of the interior of the channel bar, a tip seatable Within said recess, said tip having a cross sectional area of its exposed surface adjacent the juncture thereof with the insertible portion greater than that of a similar area of the insertilele portion, the insertible portion substantially iitting said recess, and removable means for retaining the tip in its inserted position, said means including a clip adapted to embrace the edges of the channel har and extend over the filling and the insertille portion` In witness whereof we have hereunto set our hands in the presence of two suhscrihin g witnesses.
